foreach loop : I can't see my added input - php

Question

I work with Symfony and Twig. I currently have a twig page containing a list of products, I display them with a foreach loop and I put pagination to limit the display of products.
I'm trying to put a form in this page with a checkbox as input and my problem is the following:
the checkboxes appear on all the products on the first page but when I go to the second page, I don't see the checkboxes, I need to reload the page to see them.
there is some code :
view of my loop :
<form>
<div class="row" >
{% for annonce in annonces %}
<div class="col-12 col-md-6 col-lg-4">
<p class="text text--blue text--bold m-0 text--medium mt-2">
{{ annonce._source.titre }}
</p>
<p class="m-0">{{ 'Réf' }}: {{ annonce._source.reference }}</p>
<div class="d-flex mt-2 text--bold">
<div class="d-flex me-2">
{{ annonce._source.ville }}
</div>
</div>
<div>
<input type="checkbox" name="checkbox[]" id="checkbox_pdf" value="{{annonce._id}}" multiple/>
</div>
</div>
{% endfor %}
</div>
<input type="submit" id="pdf_submit" value="Create PDF" name="submit_pdf" class="btn btn-primary">
</form>
view of the pagination :
<div class="col d-flex justify-content-between align-items-center">
<div class="d-flex">
{% if page > 0 %}
<a href="#" data-action="pagination" data-uri="{{ path('ajax_annonce_pagination',{'page':0, 'type':'frontoffice'}) }}" data-target="pagination-target">
«
</a>
<a href="#" data-action="pagination" data-uri="{{ path('ajax_annonce_pagination',{'page':page-1, 'type':'frontoffice'}) }}" data-target="pagination-target">
{{ 'Précédent' }}
</a>
{% else %}
<a href="#" disabled="disabled" >
{{ 'Précédent' }}
</a>
{% endif %}
</div>
<div>
<ul class="list-unstyled pagination m-0">
{% for i in (page+1)..(page+4) %}
{% if i <= numberOfMaxPage %}
{% if i == (page+1) %}
<li>
<a href="#" data-action="pagination" data-uri="{{ path('ajax_annonce_pagination',{'page':(i-1), 'type':'frontoffice'}) }}" data-target="pagination-target">
{{ i }}
</a>
</li>
{% else %}
<li>
<a href="#" data-action="pagination" data-uri="{{ path('ajax_annonce_pagination',{'page':(i-1), 'type':'frontoffice'}) }}" data-target="pagination-target">
{{ i }}
</a>
</li>
{% endif %}
{% endif %}
{% endfor %}
</ul>
</div>
<div class="d-flex">
{% if page < (numberOfMaxPage-1) %}
<a href="#" data-action="pagination" data-uri="{{ path('ajax_annonce_pagination',{'page':page+1, 'type':'frontoffice'}) }}" data-target="pagination-target">
{{ 'Suivant' }}
</a>
<a href="#" data-action="pagination" data-uri="{{ path('ajax_annonce_pagination',{'page':numberOfMaxPage-1, 'type':'frontoffice'}) }}" data-target="pagination-target">
»
</a>
{% endif %}
</div>
</div>
JS of the pagination :
$( document ).ready(function() {
$(document).on('click', 'a.pagination',function(e) {
e.preventDefault();
$.ajax({
url: $(this).data('uri'),
}).done(function(html) {
$('#pagination-target').html(html);
$('html,body').animate({scrollTop: $('#pagination-target').offset().top - 80}, 200);
var $scrollable = document.getElementById('pagination-target');
$scrollable.scrollIntoView();
});
});
});
In my controller I render my view like this :
return $this->render('front/annonce/list.html.twig', array(
'annonces' => $results['hits']['hits'],
'total' => $results['hits']['total']['value'],
'website' => $website,
'page' => $request->query->getInt('page')
));
What is this problem related to? is this due to the fact that it is not possible to add inputs in a looped element?
Is it related to pagination?
thanks you in advance
